Mistral Small 3.2 24B Instruct on the RX 9070

Mistral Small 3.2 24B Instruct at Q4_K_M needs about 16.2 GB, more than the 16 GB of the RX 9070: part of the model runs from system RAM, which slows generation. At Q3_K_M it fits entirely.

Frequently asked questions

Can the RX 9070 run Mistral Small 3.2 24B Instruct?
The model needs about 16.2 GB but only 15.5 GB of VRAM is usable: 0.7 GB must be loaded into system RAM. It runs, 96% on the GPU, but more slowly.
Which quantization should I use on the RX 9070?
IQ4_XS is the highest-precision quantization that fits entirely in VRAM at 8K context. ~14.7 GB / 15.5 GB.
What is the largest context on the RX 9070?
At Q4_K_M, about 3K tokens fit entirely in VRAM with an f16 KV cache. A q8_0 KV cache roughly doubles that.
How fast is Mistral Small 3.2 24B Instruct (RX 9070)?
We estimate 13–24 tok/s (estimate, confidence low). Based on: memory bandwidth (640 GB/s) and model size, system RAM bandwidth (~51 GB/s).
